As a software engineer, I decided to participate in a hardware Hackathon. I went in not knowing much about the subject, but by the end of the weekend, we made a fully functioning (somewhat janky) jacket that could roll up or roll down its own sleeves depending on what your body temperature was (inspired by Back to the Future 2). We also created a remote, so you could control the length of the sleeves as well. It was the most off-the-wall, ballin project I've ever been a part of.
